 consists of a shallow pear-shaped depression, in the anterior portion of 

 which is a small hole connected by a line each side with two similar holes 

 in the posterior portion.

ON THE OCCURRENCE OF THE TACHINID GENUS HETER- 

 OPTERINA Macq. IN NORTH AMERICA. 



By D. W. CoQUiLLETT, Washington, D. C. 



In the Annales Soc. Ent. de France for December, 1888, on 

 page 262, Bigot describes a Tachinid under the name of Heter- 

 opterina spinulosa, which he credits to North America ; this is the 

 first record of the occurrence of this genus in our fauna, and in 

 the Transactions Amer. Ent. Soc. for June, 1892, page 133, 

 Townsend discredits this generic reference, stating that the species 

 in question probably belongs to Plagia. There is a probability, 

 however, that Bigot was correct. I have recently examined 

 specimens collected by Dr. Nason, in northern Illinois, which 

 certainly belong to Heteropterina as defined by Brauer and Ber- 

 ganstamm, Schiner and Rondani. The form is a very striking 

 one, owing to the great distance intervening between the very 

 oblique hind cross-vein and the hind margin of the wing, the 

 last section of the fifth vein being longer than the penultimate 

 section ; the bend of the fourth vein is furnished with a spurious 

 vein which almost equals the apical cross-vein in length. In 

 Townsend's table of Tachinid genera (1. c) this genus would fall 

 in couplet 46, but will be readily distinguished by the characters 

 mentioned above. Judging from Bigot's description, his species 

 differs from the one now before me by its wholly black abdomen 

 and legs, besides in being nearly twice as large. The present 

 species may be characterized as follows : 



Heteropterina nasoni n. sp. (^. — Head black, face and sides of front 

 silvery white pollinose, frontal vitta grayish black, at its narrowest part 

 less than one-fifth as wide as the front; frontal bristles descending nearly 

 to middle of second antennal joint, the upper five in each row curving
